    • General method of preparation of Meldrum's acid derivative (6) Meldrum's acid (0.022 mol) and trimethyl orthoformate (0.024 mol) was added to a stirring solution of substituted aniline (5) (0.02 mol) in acetonitrile (30 ml), in succession. The mixture was heated to reflux (70°C) for 2-4 hours and then cooled to room temperature. Solvent was evaporated and the residue was purified by recrystallization for aqueous methanol. General method for thermolysis of Meldrum's acid derivative (3,4) Meldrum's acid derivative (6) was added in small batches to boiling diphenyl ether (ca. 250°C, 10-20 ml) so as to maintain a concentration of 6 under 20% by weight at any time. Gas evolution was observed instantly upon addition. Heating was continued for 0.5-1 hour after addition and the mixture was then cooled to room temperature. The product mixture was separated by column chromatography using 9% methanol/chloroform as eluent.
